angle iron.

United States Patent 0 3,132,587 Fatented May .12, 1964 Of course, the gun barrel must have an elongated rectangular passage therein. Such gun barrel is shown at 34' v 1 and the conforming passage is shown at 36. v

The cartridge case for the projectile is shown at 38.

The rear end 40 can be cylindrical, and then the forward end is crimped to conform with the angular outside periphery of the projectile, and to closely embrace the inner surfaces of the walls 22 and 24.

The present invention has the advantage of maintaining a flatter trajectory or shorter ordinate in flight with less propelling powder, and is not materially affected by,

windage.

While the form of embodiment herein shown and described constitutes preferred form, it is to be understood that other forms may be adopted falling within'the scope of the claim that follows.

I claim:

In combination, a cartridge case and an elongated projectile having the shape of an angle iron in cross section at right angles to the linear direction thereof, the fronts of the side walls thereof angle reawardly from, adjacent the front portion of the crest thereof, and the rear end of said projectile extending into the cartridge case, said cartridge case closely embracing said rear end.
